Toshiba spotlights contrast-free MRA
Providers can eliminate the use of gadolinium-based contrast by using new pulse sequences from Toshiba America Medical Systems. The angiography techniques rely on differences in the MR signal that distinguish blood and surrounding soft tissue.
Providers can eliminate the use of gadolinium-based contrast by using new pulse sequences from Toshiba America Medical Systems. The angiography techniques rely on differences in the MR signal that distinguish blood and surrounding soft tissue. The company showcased Fresh Blood Imaging, Contrast-free Improved Angiography, and Time-spatial Labeling Inversion Pulse, positioning these contrast-free imaging techniques as alternatives to gadolinium-based agents. The use of such agents has been associated with the occurrence of nephrogenic systemic fibrosis.
Multinational Study Reaffirms Value of Adjunctive AI for Prostate MRI
June 16th 2025The use of adjunctive AI in biparametric prostate MRI exams led to 3.3 percent and 3.4 percent increases in the AUC and specificity, respectively, for clinically significant prostate cancer (csPCa) in a 360-person cohort drawn from 53 facilities.
Study: AI-Generated ADC Maps from MRI More Than Double Specificity in Prostate Cancer Detection
June 5th 2025Emerging research showed that AI-generated ADC mapping from MRI led to significant increases in accuracy, PPV and specificity in comparison to conventional ADC mapping while achieving a 93 percent sensitivity for PCa.
Possible Real-Time Adaptive Approach to Breast MRI Suggests ‘New Era’ of AI-Directed MRI
June 3rd 2025Assessing the simulated use of AI-generated suspicion scores for determining whether one should continue with full MRI or shift to an abbreviated MRI, the authors of a new study noted comparable sensitivity, specificity, and positive predictive value for biopsies between the MRI approaches.
Can Abbreviated MRI Have an Impact in Differentiating Intraductal Papilloma and Ductal Secretion?
June 3rd 2025For patients with inconclusive ultrasound results, abbreviated breast MRI offers comparable detection of intraductal papilloma as a full breast MRI protocol at significantly reduced times for scan acquisition and interpretation, according to a new study.
